Abstract
Oxidative stress and neuroinflammation are involved in the pathogenesis and progression of glaucoma. Our aim was to evaluate the impact of selected single-nucleotide polymorphisms in inflammation and oxidative stress genes on the risk of glaucoma, the patients’ clinical characteristics and the glaucoma phenotype. In total, 307 patients with primary open-angle glaucoma or ocular hypertension were enrolled. The control group included 339 healthy Slovenian blood donors. DNA was isolated from peripheral blood. Genotyping was performed for SOD2 rs4880, CAT rs1001179, GPX1 rs1050450, GSTP1 rs1695, GSTM1 gene deletion, GSTT1 gene deletion, IL1B rs1143623, IL1B rs16944, IL6 rs1800795 and TNF rs1800629. We found a nominally significant association of GSTM1 gene deletion with decreased risk of ocular hypertension and a protective role of IL1B rs16944 and IL6 rs1800629 in the risk of glaucoma. The CT and TT genotypes of GPX1 rs1050450 were significantly associated with advanced disease, lower intraocular pressure and a larger vertical cup–disc ratio. In conclusion, genetic variability in IL1B and IL6 may be associated with glaucoma risk, while GPX and TNF may be associated with the glaucoma phenotype. In the future, improved knowledge of these pathways has the potential for new strategies and personalised treatment of glaucoma.

Abstract
PURPOSE Many genes have been associated with primary open-angle glaucoma (POAG). This study was conducted to investigate whether catalase (CAT) polymorphisms play a significant role in POAG in a Chinese population. METHODS A cohort of 416 unrelated POAG patients and 997 unrelated control subjects was included in this case-control association study. CAT functional single-nucleotide polymorphisms (SNPs), including rs1001179, rs7943316, and rs769217, were genotyped by SNaPshot method. The genotype and allele frequencies were evaluated using the χ2 tests. The linkage disequilibrium (LD) and haplotype block structure association were examined using the program Haploview (Broad Institute, Cambridge, MA). RESULTS There was a statistically significant difference for CAT functional SNP rs769217 between POAG cases and controls in the allelic model (p = 0.004, OR = 1.27, 95% CI 1.08-1.49). At this SNP, the allele frequency of the C allele in POAG cases was 0.587, which was higher than that in controls (0.528). However, no association was found for rs1001179 and rs7943316 with POAG. Pairwise LD analysis showed high LD between rs769217 and rs7943316 (D' = 0.857, r2 = 0.252, confidence bounds 0.71-0.93). After the association analysis for haplotype block structure generated from rs769217 with rs7943316, the data showed no significant association between the cases and controls. CONCLUSIONS This study showed that CAT functional SNP rs769217 was significantly associated with POAG, implying that the CAT gene variants may play a role in the pathogenesis of POAG in the Chinese population.

Abstract
Epidemiological studies suggest that by 2020 the prevalence of primary open angle glaucoma (POAG) is estimated to increase to 76.0 million, and to 111.8 million by 2040 globally due to the population aging. The prevalence of POAG is the highest among those of African descent, followed by Asians, and the lowest in Europeans. POAG is a genetically complex trait with a substantial fraction exhibiting a significant heritability. Less than 10% of POAG cases in the general population are caused by specific gene mutations and the remaining cases are polygenic. Quantitative traits related to POAG pathogenesis such as intra-ocular pressure (IOP), vertical cup/disc ratio (VCDR), optic disc area, and central corneal thickness (CCT) are highly heritable, and likely to be influenced at least in part by genes and show substantial variation in human populations. Recent genome-wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) at different loci including CAV1/CAV2, TMCO1, CDKN2B-AS1, CDC7-TGFBR3, SIX1/SIX6, GAS7 and ATOH7 to be associated with POAG and its related quantitative traits (endophenotypes). The chapter provides a brief overview on the different GWAS and SNP association studies and their correlation with various clinical parameters important for POAG in the population worldwide, including the Middle East.

Abu-Amero KK, Azad TA, Mousa A, Osman EA, Sultan T, Al-Obeidan SA. A catalase promoter variant rs1001179 is associated with visual acuity but not with primary angle closure glaucoma in Saudi patients. BMC MEDICAL GENETICS 2013; 14:84. [PMID: 23961996 PMCID: PMC3765135 DOI: 10.1186/1471-2350-14-84] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Accepted: 08/20/2013] [Indexed: 12/20/2022]
Abstract
Background To Investigate whether the g.4760C>T polymorphism in the promoter region of the catalase gene (CAT) is a risk factor for primary angle closure glaucoma (PACG) in the Saudi population. Methods 138 unrelated PACG patients and 403 unrelated control subjects from Saudi Arabia were genotyped for a single nucleotide polymorphism (SNP; rs1001179; g.4760C>T) utilizing Taq-Man® assay. The association between different genotypes and various clinical indices important for PACG was also investigated. Results The distribution of different genotypes was comparable between both study groups. The genotype “C/C” was predominant among cafses; 94 (68.1%) and controls; 289 (71.7%). Heterozygous genotype “C/T”, was present in 41 (29.7%) of cases and 103 (25.6%) of controls, where the homozygous variant genotype was present in only 3 (2.2%) of cases and 11 (2.7%) of the controls. The distribution of variant allele was similar in both study groups (p= 0.568). Interestingly, there was a trend of association between the type of the variant (homozygous variant, heterozygous and wildtype genotype) and one important parameter for PACG, which is visual acuity. The visual acuity increase was; 0.62 (±0.74), 0.88 (±0.88) and 1.27 (±0.95) in patients carrying the “C/C”, “C/T” and “T/T” genotypes respectively, which was statistically significant in both ANOVA and pairwise individual T tests (p = 0.022, 0.031 and 0.039) when compared to controls. Conclusions This variant is possibly associated with visual acuity in PACG patients and thus had the potential to be used as a parameter for assessing PACG severity.
